Rotation and Collision not replicating to client with CFrame?

Why is this happening: https://gyazo.com/b0bac73946b607281f2d88dc462d25a7

The rotation of the object isn't showing up in the client.

The collision of the object isn't replicating to the client

Here's the code that deals with this, target is the object which is found with mouse.Target:

Server:

local Attach = Tool:WaitForChild("Attach")
function Activate(obj)
    obj = target
    obj.CFrame = Tool.Emitter.CFrame
end
Attach.OnServerEvent:Connect(Activate)

Client:

local Attach = Tool:WaitForChild("Attach")
game:GetService("RunService").RenderStepped:Connect(function()
    if target and target.Anchored == false and target:GetMass() < 250 and (target.Position - Tool.Emitter.Position).magnitude < 10 then
            Attach:FireServer()
            obj = target
        if obj then
            obj.CFrame = Tool.Emitter.CFrame
    end
    end
end)
